ESP32 Wearable Health Band Kit: Monitor SpO2, Heart Rate & Steps
Build a Wearable Health Band with ESP32 - Monitor SpO2, Heart Rate & Steps in Real Time
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform an ESP32, a pulse oximeter sensor, and a motion chip into a wrist-worn device that reads your blood oxygen, heart rate, and daily step count - then beams the data live to your smartphone. This isn't just a breadboard experiment; you'll create a functional health band custom-coded to collect and transmit wellness data, exactly the kind of IoT wearable that appears in modern ECE labs and hackathons.
What You'll Build
You'll assemble a compact, wearable band using an ESP32 microcontroller, MAX30102 optical sensor, and MPU6050 motion chip. The finished device clips to your wrist and sends real-time SpO2, heart rate, and step count to a mobile dashboard via Bluetooth Low Energy. Walk around with it during your lab viva or project exhibition and let the live data tell the story of sensor fusion and wireless health monitoring.
What You'll Learn
- Interfacing the MAX30102 sensor with I2C to read raw PPG signals and compute SpO2 and heart rate
- Reading motion data from the MPU6050 accelerometer/gyroscope to design a step counting algorithm
- Transmitting sensor data over Bluetooth Low Energy (BLE) using ESP32's built-in radio
- Displaying live readings on a 0.96-inch OLED screen and optimizing power for battery operation

Who This Kit Is For
If you're an ECE or biomedical engineering student looking for a semester mini-project that involves real-world sensor fusion and wireless data streaming, this kit fits perfectly. CBSE Class 12 students with an interest in electronics and ATL mentors guiding health-tech prototypes will also find it ready to build. Smart India Hackathon participants developing wearable health solutions can use this as a rapid prototyping base, and B.Tech students at NIT, VIT, or BITS will have a working demo in under five hours.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to chat with the AI companion that knows every connection, sensor calibration, and BLE configuration for this project. If you prefer, message us on WhatsApp and a build expert will help within a few hours.
Can I view the health data on my iPhone or Android?
Yes, the BLE data can be received by any generic BLE scanner app, and we provide reference code to serve a simple web dashboard directly from the ESP32 so you can open it in your phone's browser without installing extra software.
How accurate is the SpO2 and heart rate measurement?
The MAX30102 provides clinical-grade PPG data with proper fingertip placement; when worn on the wrist, readings are indicative and ideal for academic demonstration, prototyping, and understanding sensor algorithms - not for medical diagnosis.
Do I need to solder anything?
No, all connections use pre-cut jumper wires and a breadboard-friendly design. The wristband holder is adjustable, and the battery is charged via the included MicroUSB cable, so you can start building immediately.
MAX30102 and MPU6050 on ESP32 measure SpO2, heart rate and steps - streams data to mobile via BLE.
